The best 20000 mAh power banks with fast charging

The 20 thousand mAh version of the Bipow power bank is positioned by the BASEUS brand as standard, along with the 10 thousand mAh lite model and the high-capacity variation - Bipow 20W 30000. In addition, the batteries offered for sale differ in design - they are available in white and black versions.

BASEUS Bipow 20W 20000 weighs about 450 grams and is 3 cm thick. At the same time, the nominal capacity of 12 thousand mAh should be enough for approximately 4 charges of an iPhone 11 or 12, as well as for 2 to 3 cycles of replenishing the capacity of Android smartphones with the most “weighty” » batteries.

The power bank is equipped with 4 ports. Only a pair of USB A with support for the Quick Charge 3.0 protocol works for the output, and microUSB works for the input. A modern “double-sided” USB C with Power Delivery 3.0 is also available. Its power reaches 20 W, which will allow, for example, to replenish up to 50% of the iPhone battery capacity in 30 minutes.

There is support for other fast charging standards, including Huawei SuperCharge Protocol or Samsung Adaptive Fast Charging, which is important for owners of mobile devices of these popular brands.

You can simultaneously connect up to 3 devices to the BASEUS Bipow 20W 20000, including those that require low current (headphones, smart watches, etc.) But in this scenario, the total power to all ports is reduced to 15 W. A convenient display that shows the current charge of the model, current strength and voltage helps to track the work.

The charging process of the powerbank itself will take a lot of time - from 6 hours. For this purpose, a cable with microUSB is included in the package. Of course, it would be better to include USB C, but even with it the input power does not exceed 18 W.

BASEUS Bipow 20W 20000 is a decent power bank if you are primarily interested in fast charging of smartphones.

The model is a universal, capacious battery for charging almost any gadget: smartphones, smart watches, fitness trackers, tablets, laptops, cameras, table lamps, portable game consoles, etc. Moreover, it allows you to simultaneously charge up to three devices, which is especially important during prolonged power outages or conditions in which there is no access to electricity at all (for example, outdoor recreation). In addition, the battery is quite capacious - 20,000 mAh. And although the actual capacity is much smaller (12600 mAh), this is still enough to charge a smartphone battery several times or provide hours of work or entertainment on a tablet or laptop.

There are three ports on the case: USB type C and two USB-A, and all of them charge devices quite quickly. USB-A has the same power - 18 W, but USB-C reaches an impressive 45 W. At this speed, it will take about 1 hour to fully charge the phone. Declared support for fast charging technologies Quick Charge 3.0 and Power Delivery 3.0, as well as proprietary Samsung Adaptive Fast Charging and Huawei Fast Charge Protocols. At the same time, a reliable protection system prevents overvoltage, short circuit and controls temperature, ensuring the safe operation of the power bank.

Not only third-party gadgets charge quickly, but also the battery itself: it is powered via the USB-C port with the same maximum power of 45 W. If you have the appropriate charger, the power bank can be fully charged in just a couple of hours. However, before purchasing, please note that only the cable is included in the package. The display on the case helps you track the remaining charge level.

Acefast's power bank is designed for users who value not only the practicality and capabilities of gadgets, but also their appearance. The manufacturer spent a lot of time on the design, adding several bright colors to choose from and the main “highlight” - a transparent “window” on the case, through which the display and some internal components are visible. It turned out interesting and unusual, although only the display, which displays information about the battery charge level, plays a useful role here.

The model is also quite compact: dimensions are 129x74x31 mm, weight is less than 400 g. For comparison, the Powerbank is smaller than almost any modern smartphone, but its thickness is comparable to two phones folded together. The body is made from fire-resistant polycarbonate (plastic), and it meets aviation standards meaning the battery can be taken on planes.

For a small size, the Acefast M2 20000 has a decent capacity - 20,000 mAh (as you guessed by the name). The actual capacity, of course, is less (about 13,000 mAh), but this is still enough to fully charge the smartphone’s battery about 3 – 4 times. In addition to smartphones, the power bank can charge a large number of other devices: tablets, smart watches, fitness trackers, wireless headphones and laptops. True, there are not many ports for this: one USB-C and one USB-A. But charging occurs quite quickly: USB-C power reaches 30 W, USB-A - 22.5 W. The battery supports popular fast charging technologies: Quick Charge 4.0+, Power Delivery 3.0, Samsung Adaptive Fast Charging and Huawei Fast Charge/SuperCharge Protocol.

The battery itself is charged via a USB-C port, which works as both input and output. In this case, the power is also 30 W, so restoring energy reserves will not take much time. A USB-C cable is included in the package.

By the way, there is also a more compact model Acefast M1 10000 on sale with a capacity of 10000 mAh.

The power bank from Xiaomi, which goes on sale at the beginning of 2022, has a laconic design made of aluminum. It looks nice, is not too heavy, and at the same time is superior in strength to its plastic counterparts.

Xiaomi Mi HyperSonic Power Bank 20000 with a capacity of 20 thousand mAh has dimensions of 154x74x28 mm, provides a single control button and a simple charge indicator with four LEDs.

The powerbank battery supports today's popular fast charging protocols, namely Quick Charge 3.0 and Power Delivery 3.0 (as well as their earlier versions). It also acquired three ports: a pair of USB A output (with a power of up to 22.5 W) and USB C. Using the latter, you can charge both the power bank itself (up to 45 W) and various connected gadgets (up to 50 W).

You can power up to 3 devices at the same time. And the replenishment time for the external battery itself is about 4 hours (USB C cable included).

Ultra-fast charging (50 W) is possible with a limited set of gadgets - Xiaomi, Redmi and Poco smartphones. So, let’s say, Xiaomi Mi 11 can be fully charged in about an hour. But thanks to support for Power Delivery technology, 45 W of power is available for any compatible devices (including laptops). For example, it is stated that the Lenovo L480 charges to 100% in approximately 2.5 hours.

In addition, there is the possibility of low-current charging. Therefore, the power bank is suitable for “feeding” energy to wireless headphones and speakers, fitness bracelets, etc.

Xiaomi Mi HyperSonic Power Bank 20000 is a universal battery that can quickly charge smartphones or even become an alternative charger for some laptops on a short trip.

Made in a laconic design, the power bank from Belkin is positioned as a travel assistant. A model with a 20,000 mAh lithium-polymer battery can charge a smartphone to 100% several times, extend the battery life of the 2019 iPad Mini by 77 hours, or extend the battery life of the 2020 MacBook Pro by at least one working day (up to 9 hours).

The USB C port offered here supports Power Delivery technology, delivers power up to 30 W and is guaranteed compatible with Apple laptops of the current model range. In addition, tests conducted by the company confirm the safety of low-current charging, that is, the model can be used with the Apple Watch and other wearable gadgets.

Belkin Boost Charge USB C PD Power Bank 20K “does not sags” in terms of operating parameters when working simultaneously with several connected devices. So, in addition to the Type-C port, there is also USB A. By using it, you can count on its maximum power, although it is limited to the standard 12 W. But in any case, 42 W per two ports is better than many competitors.

True, you also need to take into account the fact that the external battery has only two outputs (including double-sided USB C), and this is not enough by today’s standards and reduces its overall versatility.

Additional advantages of a power bank include a high level of reliability. It is confirmed by both the brand’s reputation and the warranty for the model. The warranty lasts for 2 years and even applies to connected devices. If something happens while charging your smartphone or laptop, the company is ready to cover the cost of repairing or replacing it up to $2,500.

That’s why Belkin Boost Charge USB C PD Power Bank 20K is a reliable accessory for mobile gadgets and/or MacBook.
